A new study coordinated by CU Boulder makes clear the extraordinary speed and scale of increases in energy use, economic productivity and global population that have pushed the Earth towards a new geological epoch, known as the Anthropocene. Distinct physical, chemical and biological changes to Earth’s rock layers began around […]

The first large-scale study of the risks that countries face from dependence on water, energy, and land resources has found that globalization may be decreasing, rather than increasing, the security of global supply chains. Countries meet their needs for goods and services through domestic production and international trade. As a […]
